The mod below uses "Nitrogen" as an ingredient to craft an item called "Fertilizer."
https://mods.factorio.com/mod/Bio_Industries_2 (by cackling.fiend)

Because it overlaps with the "Nitrogen" item in this planet mod, the "Fertilizer" item in the above mod cannot be crafted.
The "Nitrogen" item in the above mod uses a fluid called "liquid-air," but this recipe doesn't appear on Factorypedia.
On Factorypedia, only the "Nitrogen" recipe from this planet mod appears.

I reported this to the "Bio Industries" mod, but the author stated that they don't currently support the Space Age and advised me to contact the planet mod author if they would support "Bio Industries."
So, I'm reporting this here as well.
Actually, this overlaps with other planet mods that use the "Nitrogen" item, so I've reported it on the respective planet mod forums.
Would it be possible to add compatibility?
Thank you for making such a great mod.

You more than likely have the "Vesta independent gases" option turned on which makes all the gases on this mod (hydrogen, nitrogen, oxygen, etc) only work on Vesta. The fluids will get the prefix "vesta_" added onto them, so instead of "nitrogen", you get "vesta_nitrogen"; I added this in order to prevent breakage with other planets in the event a modpack author wanted to prevent cheesing other planets by exporting the gases. You will need to turn this option off; however, do note that you will have to manually reset all your machines and tanks. "Vesta independent gases" option is not turned on by default as the default is with it off.

The Vesta Independent Gas option is disabled. The only option I have enabled is the composite mode option below it.
